Incident Management: Checklist, Tools, and Prevention

This article summarizes incident management and how to deal with and survive an outage that occurs in your software.

What Is Incident Management?

Incident management is the process of identifying, responding, resolving, and learning from incidents that disrupt the normal operation of a service or system. An incident can be anything from a server outage, a security breach, a performance degradation, or a customer complaint. Incident management aims to restore the service as quickly as possible, minimize the impact on users and the business, and prevent the recurrence of similar incidents.

Incident Management Checklist

Incident management can be a complex and stressful process, especially when dealing with high-severity incidents that affect a large number of users or have a significant business impact. To help you navigate the incident management process, here is a checklist of the main steps and best practices to follow:

• Prepare: Have a clear and documented incident management policy and procedure, define roles and responsibilities, establish communication channels and tools, and train your team on how to handle incidents.
• Detect: Monitor your systems and services for any anomalies, alerts, or errors, and have a mechanism to report and escalate incidents.
• Respond: Assign an incident commander and a response team, communicate the incident status and impact to stakeholders, and coordinate the actions to contain and mitigate the incident.
• Resolve: Identify the root cause of the incident, implement a permanent fix or a workaround, and verify that the service is fully restored and stable.
• Review: Conduct a post-incident review, document the incident details and timeline, analyze the incident causes and effects, and identify the lessons learned and action items.
• Improve: Implement the action items from the post-incident review, update your incident management policy and procedure, improve your monitoring and alerting systems, and share your knowledge and best practices with your team and organization.

Problem Management vs. Incident Management

Problem management and incident management are two related but distinct processes in IT service management. While incident management focuses on restoring the service as quickly as possible, problem management focuses on finding and eliminating the underlying cause of the incident. Problem management can be proactive or reactive, depending on whether the problem is identified before or after an incident occurs. Problem management can help prevent future incidents, reduce the frequency and severity of incidents, and improve the service quality and reliability.

DevOps and SRE Incident Management Process

DevOps and SRE (Site Reliability Engineering) are two approaches that aim to improve the collaboration and efficiency of software development and operations teams. Both DevOps and SRE emphasize the importance of incident management as a key aspect of delivering reliable and resilient services. DevOps and SRE share some common principles and practices for incident management, such as:

• Blameless culture: Foster a culture of trust and learning, where incidents are not seen as failures or opportunities to blame, but as opportunities to improve and prevent future incidents.
• Automation: Automate as much as possible the incident detection, response, resolution, and review processes, using tools such as monitoring, alerting, incident management platforms, chatbots, runbooks, etc.
• Collaboration: Involve the right people from different teams and disciplines, and use tools such as chat, video conferencing, screen sharing, etc. to facilitate communication and coordination.
• Feedback: Collect and analyze data and feedback from incidents, such as metrics, logs, traces, surveys, etc. and use them to measure and improve the service performance, availability, and reliability.

Incident Management Tools

Incident management tools are software applications that help you manage and streamline the incident management process. They can help you with various aspects of incident management, some of the popular industry-wide tools are: 

Case Study: Applying Incident Management Best Practices at “Sell Fast”

“Sell Fast” is a fictitious e-commerce company that has recently experienced an unexpected outage, affecting its sales and customer experience. This case study aims to summarize the incident management best practices discussed in the previous article and apply them to this real-world scenario.

Incident Management at “Sell Fast”

One day, “Sell Fast” started experiencing slow page load times, leading to a drop in sales and customer complaints. This was identified as an incident. Here’s how they applied the incident management best practices:

1.     Incident Identification: The company’s monitoring systems detected the slow page load times and alerted the IT team.

2.     Incident Categorization: The IT team categorized this as a "performance issue."

3.     Incident Prioritization: Given the direct impact on sales and customer experience, this incident was given high priority.

4.     Incident Assignment: The incident was assigned to the performance optimization team, who had the expertise to handle such issues.

5.     Incident Diagnosis: The team started investigating. They found that a recent update to the product recommendation algorithm was making complex database queries, causing the slowdown.

6.     Incident Resolution: The team implemented a workaround by reverting the algorithm to its previous version. This restored the page load times to normal.

7.     Incident Closure: After confirming the resolution, the incident was closed.

8.     Incident Review: A post-incident review was conducted. The team found that the updated algorithm was not adequately tested for performance. They decided to include performance testing as a mandatory part of their software development process.

Preventing Future Incidents

To prevent such incidents in the future, “Sell Fast” took several proactive measures:

1.     Automated Testing: They implemented automated performance testing for all updates to their website.

2.     Load Testing: They started conducting regular load testing to understand how their website performs under high traffic.

3.     Redundancy: They implemented redundancy for their servers to ensure that their website remains available even if one server fails.

4.     Training: They trained their team on best practices for performance optimization.

By following these steps, “Sell Fast” was able to effectively manage the incident and also take proactive measures to prevent similar incidents in the future. This case study serves as a practical example of how incident management and prevention can help maintain a high-quality user experience.

Conclusion

While it’s important to have effective strategies for managing incidents, the ultimate goal should be to prevent them from occurring in the first place.

The case study of “Sell Fast” serves as a practical example of how these best practices can be applied in a real-world scenario. It highlights the importance of learning from incidents and continuously improving the incident management process.

In conclusion, effective incident management not only helps in surviving incidents but also in preventing them, thereby ensuring a smooth and high-quality user experience. Remember, every incident is an opportunity to learn and improve. Happy incident managing!
